Problems solved by technology
Using the time-difference method as a traditional flow measurement principle, there are some uncertainties in flow measurement by the time-difference method due to factors such as difficult installation, high mechanical manufacturing accuracy requirements, and high requirements for time interception accuracy.
Although the electromagnetic flowmeter is not affected by the temperature, viscosity, etc. of the fluid and the liquid-solid composition ratio, it cannot measure gas, steam, and liquids containing a large amount of gas.

The invention discloses an ultrasonic Doppler pipeline flow velocity measuring device. The device comprises a Doppler frequency shift signal receiving and processing module, the Doppler frequency shift signal receiving and processing module receives ultrasonic signals of a receiving transducer, and sends the ultrasonic signals to a processor through a zero waveform adjusting circuit to carry out digital signal processing and then obtain the frequency shift amount, and a transmitting circuit can sends ultrasonic waves to the receiving transducer through a transmitting transducer. Thus, the flowvelocity of petroleum oil in a pipeline can be rapidly and accurately measured, flow of liquid in the vertical pipe can be adjusted, the liquid production rate is improved, flow in the horizontal pipeline is adjusted to the economic flow velocity, and the oil transportation efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of petroleum engineering pipeline transportation, and in particular relates to an ultrasonic Doppler pipeline velocity measuring device. Background technique [0002] With the rapid development of the petroleum industry, the development and production management of oilfields is gradually developing towards intelligent management, and has been widely promoted and applied. Using the transit time difference method as a traditional flow measurement principle, there are some uncertainties in the flow measurement by the transit time difference method due to factors such as difficult installation, high precision requirements for mechanical manufacturing, and high requirements for time interception accuracy. Although the electromagnetic flowmeter is not affected by the temperature, viscosity, etc. of the fluid and the liquid-solid composition ratio, it cannot measure gas, steam, and liquids containing a large amount...
